一、概述硬质合金钎头是采掘工业必不可少的工具之一。如何研制高效率、高质量的新型钎头,是同行们极为关注的重要问题,不少单位巳作出了贡献。我们自1979年起,与武汉地质学院钎头科研组协作,共同研制新型钎头,也取得了较好的技术经济效果。新一字马蹄形钎头已在十多个矿山中得到应用,取代了老一字钎头。同时,我们还研制了三刃、十字、球齿等不同规格类型的钎
I. Overview Carbide drill bit mining industry is an essential tool. How to develop a new type of drill head with high efficiency and high quality is an important issue that our colleagues are extremely concerned about. Many units have made their contribution. Since 1979, we have cooperated with the Scientific Research Team of Brazing Head of Wuhan Institute of Geology and jointly developed a new type of brazing alloy and achieved good technical and economical results. The new word horseshoe bit has been used in more than a dozen mines, replacing the old word bit. At the same time, we also developed a three-edged, cross, ball and other types of brazing different specifications
